我们提出了一种基于Pearce Hall （Pearce & Hall, 1980）经典条件反射模型的潜在抑制理论。它的核心特征是：(1)刺激的联想性在预测其结果时下降；(2)非强化的刺激暴露会参与联想学习过程，使刺激成为其结果的准确预测器（在这种情况下，没有事件的发生）。这一理论的一个形式化证明了与另一个线索复合的预暴露可以增强对目标线索的潜在抑制的发现。它进一步预测，预先暴露于增加的线索将消除增强效应。一项用老鼠做的实验和厌恶味道的过程证实了这一预测。
We present a theory of latent inhibition based on the Pearce Hall (Pearce & Hall, 1980) model for classical conditioning. Its central features are (1) that the associability of a stimulus declines as it comes to predict its consequences and (2) that nonreinforced exposure to a stimulus engages an associative learning process that makes the stimulus an accurate predictor of its consequences (in this case, the occurrence of no event). A formalization of this theory is shown to accommodate the finding that preexposure in compound with another cue can potentiate latent inhibition to the target cue. It further predicts that preexposure to the added cue will eliminate the potentiation effect. An experiment using rats and the flavor-aversion procedure confirmed this prediction.
